FFTQE DELOS HAMMER, OF HIGH POINT, NORTH" CAROLINA.

TYPE-WRITER ATTACHMENT.

To all whom it may concern:

Be it known that I, DELOS E. HAMMER, a citizen of the United States, residing at High Point, in the county of Guilford and State of North Carolina, have invented new and useful Improvements in Type-VVriter Attachments, of which the following is a specification.

. This invention relates to an improved copy holder for typewriters and is designed to provide means whereby the lines of the copy will be properly spaced and also where: by, when the spacer member is brought to the lowermost line of the copy, the device may be actuated to turn the page of the copy book and return the spacer to the first line to be copied from the adjacent page of the said copy holder.

In. carrying out my invention it is my purpose to construct a device of this character which may be easily and quickly connected to the typewriting machine and easily and quickly operated by the typist.

Itis also my purpose to produce a device of this character which shall embody the desirable features of simplicity, efliciency and accuracy.

\Vith the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings:

Figure 1 is a side elevation illustrating the arrangement of the improvement upon a typewriter, v I

Fig. 2 is a rear view, of the same, Fig. 3 is avertical sectional view approximately on the line 33 of Fig. 2,

Fig. ,4 is a top plan view,

Fig.- 5 is a sectional view substantially similar to Fig. 3 but illustrating the table folded 'rearwardly of the typewriter,

F ig.. 6 is an enlarged sectional View through the spacer bar, and

Figs. 7 to 9 illustrate details.

The improvement may include aflatbase 1', and if desired the typewriter machine 2 mayrest upon this base, the said base extending rearwardly of the machine. Rising from the base adjacent to the rear thereof is a plurality of uprights 3, the enduprights being spaced from each other a distance appfi' xingately equaling the depth of the ma- 0 me .leurnal d up nsertaincf thsrprigh s 3 Specification'of Letters Patent.

adjacent to the top and bottom thereof are shafts 5 and 6 respectively. The shaft 6 has secured thereto a toothed or ratchet wheel 7 which is arranged outwardly of one of the end uprights 3, while upon the said shaft inward of the referred to end upright is a grooved wheel 8. The shaft 5 has secured thereon a grooved wheel 9, and upon the periphery of this wheel is wound and secured a belt or flexible member 10 which is also wound around and secured to the wheel 8. Upon the referred to end upright 3, be-- yond which the toothed or ratchet wheel 7 is" arranged, I'pivotally secure, as at 11, a spring member in the nature of a dog 12, the said dog co-acting with the teeth of the wheel 7. Upon the base 1 I arrange in suitable bearings 1313, a longitudinally disposed operating rod 14, the same having its outer end provided with a knob or handle 15 and its inner end engages with one of the teeth of the wheel 7 whereby when the rod is moved longitudinally in the direction of the wheel, the said wheel will be rotatedand consequently turn the shaft 6 to actuate the belt 10 and revolve the wheel 9, thepurpose of which arrangement will presentlybe described.

' Upon the rod 14, and disposed adjacent one of, the bearings 13 for the said rod I arrange an adjustable stop member 16 which, when contacting with the said'bearing 13, will limit the longitudinal movement of the rod in the direction of the wheel 7.

The rod 14 is provided with an offset member or lug l7 and the said rod between thelug 17 and the inner bearing member 13 has arranged thereon a helical spring 18, oneend of the said spring being-secured to the lug 17 and the other end bearing against or if desired secured to the bearing member 13. The spring 18 normally moves the rod a predetermined distance in an outward direction sothat its engaging end will not forcibly-contact with the teeth of the wheel 7, while the inward movement of the rod, in a direction for turning the wheel 7, is limited by the stop member 16, as previously set forth. I

The lug member:17 is provided with an opening through which passes a rod member 19 that has its outer end provided with a head 20 and its'inner end secured to the spring dog12, as illustrated by the drawings. The basefl, to the rear of the ratchet Wh elT; has ranged therean pa e P s tween the plates '21" and 22 when the rod 21 and 22 respectively, the plate 22 having its upper face beveled and extending: longitudinally along the sides thereof isa spring strap 23, the same comprising acurved or arch-shaped member and adapted to haveitsend received-in.the notch or space bemember 14 is pulled outwardly to-bring'the end thereof out of engagement with the teeth of the ratchet wheel37 to cause the-lugs 17 to contact with thehe-ad 20'of the member 19 to release the dog 12, the purpose of which arrangement will presently be appar- Secured upon theshaft 5 is a grooved wheel 24 and extending horizontally from the frame provided by the uprights 3 at a suitable distance'above the typewriter is a supportingmember 25; Through this member-25 passes a pivot 26 and this pivot has journaled' thereon one or more segmental tooth" racks 27 ,the said racks being engaged by springpressed dogs 28 and the said racks supportthe table 29 upon which the copy is adapted to rest. Asshown in Fig. 7 of the drawings, the spring'pressed dog '28 is provided 'with an operating handle 28', wherebythe dog may be swung out of engagement with the toothed segment 27 to permit of the angular adjustment of the table 2 9 with respect to the members- 26 and to the standards 8.

The spacer member which works upon the outer face of'the table is indicated by the numeral 30"and comprises an element shaped to include a fiat und'erface; 31, a rear face 32 which is preferably slightly rounded, the said face 32 beingprovided with a facing or coating of some suitable compressible material, such as rubber, which is indicated by the numeral 33 and if desired the face 32' may be provided with slight projections in the nature of pointedelements. 'The outer face of the spacer member 31 is rounded, as-indicated by the nu-' meral34 and said member 34 at s'pacedintei vals is provided with depressions; orsockets 35 through which pass pivot members-36 from its outer end to its pivot 43" as'indicat'e'd by'the numeral 45, and if desired the straight end of the lever maybe retained betweenthe, plates 21 and 22 through;the:me-' dium of 'a spring-4'6 eXertin-g'a pressnre be tweenthebase' an d' tlie "angular endof-ithe levee ""Jllhe; angular end-of-"the lever-is.

disposed in the path of contact withthe weight 42, and the operation of the device may be briefly described as follows: The bookqor tablet is arranged upon the table 29 so that the spacer member is disposed over the outer page thereof. The spacer member is moved to the top of the table When-a pressure upon the handle 15 will rotate the ratchet wheel 7 and consequently the shaft 6 draws the belt' 10 around the wheel 8- cau'singthe wheel 9'to be; revolved and as a consequence permitting theweighted spacer member to gravitate over the inclined tabletoward the outerend thereof the movement of the-spacer being-regulated by the element 16- connected' with the rod.- When the spacer member has been moved to the end of the copy book or tablet upon the table; the operator pulls the rod 14 outwardly and in so doing draws the member-19 to bring'the dog 12. out ofengagement withthe teeth of theratchet wheel and the member. 23 is arranged within the notch 01': space between the plates 21 and 22 and over'the straight: end of the lever 44. It is to be understood that: the weight 42 is heavier than the combined weight of the frame providedby the members 38 and 40 and thesp'a'cer- 31 so that when the parts arereleased as just described the weight will travel overthe wheel 24' drawing the spacer upwardly-ofthetable. By reason of the peculiarformati'onof the ends of the' member 38'and their pivotal engagementflin the notches provided :upon the outer face of the spacer member 31 and alsoinconsideration of the rounded: corner between "the curved face and the fiat face-3120f the said spacer; A movement of-the spacer in a rearward direction: will cause the same to be swung to bring its flat face 31 out of engagement with the copy an'd'itscompressible face 33'over thecopy. The sharpened-mem bers indicated by thenumerals 4'7 ',1up'on the face 33 will engage with a page of the-copymoving the same inwardly over the rear edge O'fthe table land so folding the used page of thecopy overthe ba'ck 'of the-table;

When the parts are'brought'to this position 1 the weight-42 will contact'with the-angular end 45" of theme'mber 44 swinging the same upon its pivot and bringing the member 23' from betweenthe-"plates-21 and 22 permitting the spring- 18 to: exerta tensionand force the rodrearwardly-or in the direction of 'the ratchet wheel 7 wherebythe spring dog 12" will again engage withthe-ratchet wheel to prevent the :turning of f the' ratchet' 7 wheel in a retrograde direction.

' If desired one of the; members 38 or the connecting bar or-rod 40 may be-provided with astraight extension 7 49' which; passes through a'xslot; '50 formed upon: a member 51 that is secured to the frame formed'iby" t the uprights-3, and bye-this:arrange e t it 5 will be noted that the spacer bar will be at all times properly arranged'upon the table or upon the-copy arranged upon the table. It will be also noted that by providing the toothed segments in the spring dogs operated by the member 31, the table 29 may be swung upwardly of the typewriting ma chine, to permit of the operator properly arranging the paper inthe machine.
